As the standard deviation (σ) decreases, the width of the confidence interval .

When there is the decrease in the standard deviation so the width of the confidential interval should be increased.

Given that,

Based on the above information, the following information should be considered.

Therefore we can conclude that when there is the decrease in the standard deviation so the width of the confidential interval should be increased.

increases

Step-by-step explanation:

The width of the confidence interval decreases as the sample size increases.

(x3 + 6x2 + 2x - 6) • (x - 1)

step-by-step explanation:

polynomial long division :

3.2     polynomial long division

dividing :   x4+5x3-4x2-8x+6

                              ("dividend")

by         :     x-1     ("divisor")

dividend     x4   +   5x3   -   4x2   -   8x   +   6

- divisor   * x3     x4   -   x3            

remainder         6x3   -   4x2   -   8x   +   6

- divisor   * 6x2         6x3   -   6x2        

remainder             2x2   -   8x   +   6

- divisor   * 2x1             2x2   -   2x    

remainder               -   6x   +   6

- divisor   * -6x0               -   6x   +   6

remainder                     0

quotient :   x3+6x2+2x-6   remainder:   0
